john the ripper 1.7.4 dev dispo en download

Depuis peu sur le site d'openwall, la version de développement john the ripper est disponible, ce qui fait que la stable est en version 1.7.3.3 (pas changé) et la version dev en 1.7.4 avec evidemment de nouvelles options.

changelog:
The following changes have been made between John 1.7.3.4 and 1.7.4:

* Support for back-references and "parallel" ranges has been added to the
word mangling rules preprocessor.
* The notion of numeric variables (to be used for character positions
and substring lengths along with numeric constants supported previously)
has been introduced into the rules engine. Two pre-defined variables
("l" for initial or updated word's length and "m" for initial or
memorized word's last character position) and 11 user-defined variables
("a" through "k") have been added. Additionally, there's a new numeric
constant: "z" for "infinite" position or length.
* New rule commands have been added: "A" (append, insert, or prefix with a
string), "X" (extract a substring from memory and insert), "v" (subtract
and assign to a numeric variable).
* New rule reject flags have been added: ":" (no-op, for use along with the
"parallel" ranges feature of the preprocessor) and "p" (reject unless word
pair commands are allowed, for sharing of the same ruleset between "single
crack" and wordlist modes).
* Processing of word mangling rules has been made significantly faster in
multiple ways (caching of the current length, less copying of data, code
and data placement changes for better branch prediction and L1 cache usage,
compiler-friendly use of local variables, code micro-optimizations,
removal of no-op rule commands in an initial pass).
* The default rulesets for "single crack" and wordlist modes have been
revised to make use of the new features, for speed, to produce fewer
duplicates, and to attempt additional kinds of candidate passwords (such
as for years 2010 through 2019 with "year-based" rules).
* The idle priority emulation code has been optimized for lower overhead when
there appears to be no other demand for CPU time.
* The default for the Idle setting has been changed from N to Y.

Après si vous voulez cracker votre pass root sur une fedora, ubuntu récente (et d'autres) c'est du sha512 ca ne passera pas, il faudra patcher john, comme indiqué dans ce precedent post: cracking root password, sha512
